DETAILED DESCRIPTION

Various detailed embodiments of the present disclosure, taken in conjunction with the accompanying figures, are disclosed herein; however, it is to be understood that the disclosed embodiments are merely illustrative. In addition, each of the examples given in connection with the various embodiments of the present disclosure is intended to be illustrative, and not restrictive.

The term ‘baby’ hereinafter may refer to the subject of the system. The term baby may refer to a newborn, infant or toddler, but the baby may be a child, adult, or elderly person in need of care or stimulation, or it may be an animal, such as a pet that may become noisy when bored or an animal in a veterinary care facility.

The term ‘user’ hereinafter may refer to a person employing the system to monitor and care for a baby and also to provide stimulation, instruction or development tools for the baby.

Embodiments of the present disclosure herein describe a computer-based system for monitoring and interacting with a baby and methods of use thereof. The system may be implemented with artificial intelligence (e.g., machine learning models) that may collect data and may personalize a full ecosystem of synergies in data collection functionality and feedback, thereby providing a personalized care system. The system may be configured for care of newborns, infants and toddlers. The system may be configured for use with humans and may be configured for use with a member of a group of children, adolescents, adults, the elderly or any combination thereof.

In the educational use case 156, the baby-specific educational machine learning model may be trained to output (1) an indication that the baby understood or did not understand the visual image and audio output associated with the visual image (see FIG. 2D), and (2) a baby-specific educational recommendation based on the understanding indication. In response to the output of the baby-specific educational machine learning model, the processor 60 may then execute, based on the baby-specific educational recommendation(s), at least one of: (1) a modification of the at least one baby-specific educational plan when the at least one indication indicates that the at least one baby did not understand, or (2) a continued execution of the baby-specific educational plan for the at least one baby, for example.

FIG. 4A is a first exemplary list 160 of input-output data features in a dataset for training the baby-specific behavioral state detection machine learning model and/or the baby-specific educational machine learning model in accordance with one or more embodiments of the present disclosure. The input features 163 for the input feature categories 162 and the output features 165 for the output feature categories 164 in the table shown in FIG. 4A are directed to the soothing use case 154 and educational use case 156. Although the first exemplary input-output dataset 160 may illustrate 30 different features, for example, this is merely for conceptual clarity and not by way of limitation of the embodiments disclosed herein. The input-output training sets may include 1000 features, 10,000 features, or 100,000 features.

FIG. 4B is a second exemplary list 170 of input-output data features in a dataset for training the baby-specific behavioral state detection machine learning model in accordance with one or more embodiments of the present disclosure. The input features 174 for the input feature categories 173 and the output features 176 for the output feature categories 175 in the table shown in FIG. 4B are directed to the feeding use case 152. Although the second exemplary list 160 may illustrate 20 different features, for example, this is merely for conceptual clarity and not by way of limitation of the embodiments disclosed herein. The input-output training sets may include 1000 features, 10,000 features, or 100,000.

With regard to lists of input (stimuli) feature data and output (response) feature data shown in the tables of FIGS. 4A-4B, the inputs 163 and 174 show examples, without limitation, of the baby-specific stimuli data including but limited to environmental data such as weather, time of day, room light intensity, temperature, humidity, etc; baby-specific physiological data such as but not limited to breathing rate, movement heatmap, pacifier presence etc. These inputs may include baby-specific personal data such as for example without limitation, age, height, weight, pregnancy length, and the like.

In some embodiments, the baby-specific response data or the output features 165 and 176 may include for example, doing nothing, notify user, stop current action, play a video file on the projector 18, increase/decrease light, increase/decrease temperature, change smell, change vibration rhythm, and the like.

In some embodiments, any electronic resource from the plurality of electronic resources 110 may store in any of the N databases 112: (1) a plurality of baby-specific educational plans for a plurality of babies, (2) baby-specific stimuli data for a plurality of baby-specific stimuli provided to the plurality of babies, (3) baby-specific response data for a plurality of baby-specific responses acquired in response to the plurality of baby-specific stimuli provided to the plurality of babies, and (4) baby-specific personal data for each baby in the plurality of babies.

Note that the system 5 may query the electronic resources to retrieve the data from a plurality of babies. The baby-specific stimuli data and the baby-specific response data from the plurality of babies may also be referred to herein as crowdsourcing data, or infant crowdsourced data that may be data associated with other babies using the system 5 via a server 100, from laboratory experiments, or any combination thereof.

In some embodiments, the data from the electronic resources 110 may be used to create datasets for training any of the machine learning models and/or algorithms as discussed herein. Thus, when inputting data associated with a specific baby into each of the machine learning models as discussed herein, the output data from each of the machine learning models incorporated the data (e.g., the learning) from a large population of babies on the order of 100 babies, 1,000 babies, 10,000 babies, or 100,000 babies.

In some embodiments, the baby-specific stimuli data from the plurality of babies may also include the simulated baby-specific physiological data for the plurality of babies. For example, image data from an image camera that images the baby and audio data from a microphone or sound transducer sampling the voice of the baby and/or sounds emitted from the baby may be processed to simulated or compute baby-specific physiological data such as heartbeat data (see algorithms associated for example, with FIGS. 10-14) and/or breathing data (see algorithms associated for example FIGS. 15-19), for example. This simulated data may also be included in the datasets.

In some embodiments, in order to generate the training dataset, the baby-specific stimuli data and the baby-specific response data for each baby from the plurality of babies, the data stored databases in the electronic resources may include the same data as that shown in the exemplary lists of FIGS. 4A-4B, from which the sensor data, image data and/or audio data features may be extracted for each baby to train the machine learning models.

In some embodiments, the breathing rate signal data may be simulated using the algorithms associated with FIGS. 15-19. In short, the image (video) data and/or the audio data of the baby may be used to identify pixels in the image associated with the baby's chest region and to monitor those identified pixels in time for characteristic periodic breathing movements. From this pixel change analysis, the breathing rate may be calculated. If there are no characteristic periodic breathing movements detected, the system 5 may generate a notification such as an alert on the GUI 55 that the baby is not breathing.

In some embodiments, the spatial body temperature distribution data may be acquired from an IR array thermal imaging camera such as for example, MLX90640 IR Array Thermal Imaging Camera, 32×24 Pixels, 110° FOV from Waveshare Electronics World Trade Plaza south side, Fuhong Rd, Futian District, Shenzhen, 518033, China. When the thermal imaging camera is positioned to image the baby and may also capture objects in the baby's immediate environment such as for example, the baby's blanket, the output data from the camera may be a spatial mapping of the baby's external body temperature at different locations on the along the contour of the baby's body and the temperature at certain spatial points along the contours of the objects in the baby's environment.

In some embodiments, the heartbeat signal data may be computed by applying algorithms related to FIGS. 10-14 described hereinbelow to the image (video) data of the baby. The baby heartbeat signal data may be, for example, the computed heartbeat signal h_(i)(t) 3465 as referenced in FIG. 11E hereinbelow.

In some embodiments, the baby motion data (e.g., the movement heatmap and/or the movement power of the baby's motions) may be derived from the image (video) data and/or the spatial body temperature distribution data. Pixel change algorithms may be applied to the video data, for example, that may be used to track pixels in time to identify the movement power where low power movements are defined as small movement motions of the baby, and high-power movement are defined as large movement motions of the baby such as the baby flipping over, for example. In other embodiments, anatomical movements of the baby (head, shoulders etc) also known as skeleton detection algorithms of the baby may be used detected movements of the baby.

In some embodiments, the baby voice classification data may include the baby's voice rate, voice magnitude, voice type (a cry, a cry when hungry, a cry for attention, mumbling, choking, coughing, swallowing, etc) and voice pitch, for example, that may be determined by applying a classification model and/or a genetic classification to the raw audio data.

Note that the input-output data features in FIGS. 4A and 4B for the baby-specific features and the environmental-specific features for each use case are related to the baby-specific stimuli data and baby-specific response data stored in the databases of the electronic resources. For example, the baby-specific stimuli data (e.g., baby-specific features 225) may include baby-specific personal data, breathing detection data, heart rate detection data, baby voice data, baby temperature data that may be representative of the baby's behavioral state as well as the environmental-specific features 230 at any instant of time that may be inputted to the machine learning models. Thus, the baby-specific response data may be indicative of the baby's response or actions to change the behavioral state of the baby. When this data is used to train the machine learning models, the machine learning models may incorporate the environmental stimuli and the baby's behavioral state in the baby-specific stimuli data for each baby in the plurality of babies so as to output the actions, recommendations, notifications and/or behavioral state indications to change the baby's behavioral state for each baby from the plurality of babies.

In some embodiments, the output data generated from the plurality of sensors 80 may be pre-processed using different pre-processing algorithms to generate the input data features for training the machine learning models. For example, the output data of the image camera 81, the thermal imager 83, the lidar device 84 and/or the RF device 85 may be used in algorithms disclosed hereinbelow that may determine the breathing and heart rate of the baby 15 over time. The processor 60 may use the output data from the plurality of sensors 80 in the 3D map generation module 61 to generate a 3D map of the baby 15 as a function of time so as to generate a movement heatmap and/or movement power. The machine learning models may be trained to output different actions and transmit instructions to the different peripheral/IoT devices. These actions may include but are not limited to playing an audio file with time varying parameters such as the varying volume, frequency of the audio signal and the like (e.g., equalizer), playing a video file and varying projection brightness, for example, to apply a vibration intensity and vibration pattern to the baby 15 via the vibration unit 40, to change the room light 28 (e.g., control the illumination lamp 27 to vary the light color and illumination intensity), and/or to change the room temperature, humidity, air pressure, changes in smell in the sensing region 12 by the BMID 10 varying different IoT device states controlling a thermostat, a humidifier, actuators to open/close windows, activate a fan, the foodstuff temperature controller 35, and/or aromatherapy devices in the baby's room, for example.

In some embodiments, the system 5 may collect data through the plurality of sensors 80 from the baby such as, for example, behavioral data, and may provide stimulation or soothing through the peripheral/IoT devices after processing the behavioral data by the MLM/algorithm module 65. For example, changes in the baby's breathing rate or changes in its crying, the baby's sleeping and waking patterns may be determined. The system may then react to the baby's behavior patterns, providing stimulation when appropriate and soothing (e.g., reducing the baby's level of agitation, or irritability) when appropriate. In some embodiments, the system 5 may detect that the baby is hungry. The system 5 may prepare the foodstuff (e.g., warming up the baby bottle 32 by the temperature controller 35) and then the user 45 may be alerted via a mobile device 50 such that when the user 45 arrives to the baby 15, the foodstuff is ready to feed to the baby 15 (e.g., at the correct predefined temperature).

In some embodiments, if the system 5 detects, based on both video and audio analysis, that the baby is tired or uncomfortable, the system 5 may be configured to soothe the baby using an AI-based soothing system by playing soothing music, providing vibrations, and/or projecting images to the baby. In other embodiments, the system 5 may determine whether the baby's level of discomfort may be reduced by soothing only. In yet other embodiments, the system 5 may determine using the AI-based algorithms to send an alert via the GUI 55 to the user 45 that attention needs to be given to the baby.

In some embodiments, if the system 5 assesses that only soothing is needed, the system 5 may automatically start playing a comforting sound. The comforting sound may be chosen to be optimal for that baby, that is the tune, volume, and/or play duration, for example, may be AI-tailored to the baby. In other embodiments, both the comforting sound and the volume may be adjusted as needed, based on the baby's responses. The sound may be a tune, white noise, a hum, a pre-recorded voice of a parent, grandparent or caregiver, or any combination thereof. In other embodiments, the machine learning model may output the soothing sound to be generated by the speaker to the baby 15.

In some embodiments, system 5 may implement a baby-specific soothing procedure (e.g., tailored to a particular baby) that may include the following steps:

-   -   1. Crying may be detected (via audio and/or video).     -   2. At least one of a sound, video, image or vibration may sent         to calm the baby. In some embodiments, the sound, video, image         or vibration may continue to be played until the baby is asleep.     -   3. The baby's behavior may be sampled by the system 5, such as         for example in predefined time intervals.     -   4. If system 5 detects that the baby has not calmed down (or is         not asleep), the system 5 may change at least one: a sound         played to the baby, a video or image projected for the baby to         see, and/or a vibration applied via a vibration unit such as a         vibration mat. For example, one or more additional sounds,         videos, images and/or vibrations may be added. A volume of the         sound may be made to be louder or softer. The type of sound may         be changed (change tune, change caregiver recorded voice, change         what the caregiver is saying, change to white noise, change to         hum, etc.). Similarly, a vibration applied to the baby may be         made stronger or weaker, or the type of vibration may be         changed. A video or image displayed to the baby may be changed.         The display of the video or image may be made brighter, paler,         stronger or weaker. A colored image may be recolored.     -   5. The system may recheck or re-sample the baby's behavior         (changes in crying noise/breathing rate, etc.)     -   6. Repeat steps 4 to 6 until the baby calms down (or falls         asleep).

In some embodiments, the system 5 may improve the machine learning models/algorithms 65 by retraining them so as to model the real-time behavior of a particular baby. Thus, the system 5 may start a future soothing procedure from a known starting point when the baby needs to be soothed again since the retrained model has already captured what kind of actions, such as sound, illumination, projected images, vibration, etc that worked previously to soothe the particular baby.

In some embodiments, the system 5 may query data from at least one electronic resource store 110 baby-specific stimuli data for a plurality of baby-specific stimuli provided to a plurality of babies as well as baby-specific response data for a plurality of baby-specific responses acquired in response to the baby-specific stimuli provided to a plurality of babies. Thus, the system may train the machine learning models using the data from the plurality of babies that may capture, for example, what works better for babies with similar characteristics to a particular baby. The system may be configured to dynamically adapt the solution to each child.

In some embodiments, the system 5 may be configured to predict increases in the baby's stress levels and to automatically execute solutions outputted by the machine learning models to reduce the baby's stress.

In some embodiments, a monitoring subsystem (e.g., may include a two-way audio system) may be detachable from the main system (e.g., the BMID 10) and may be portable so that the soothing system may be used when the baby is not in the presence of the main system such as for example, when the baby is in a stroller or in a vehicle but communicative coupled via wired or wireless communication protocols. In other embodiments, the monitoring subsystem may include a battery or any suitable power storage device. In yet other embodiments, the monitoring subsystem may be docked to the main system for recharging, and/or may be connected to at least one conventional powering system.

In some embodiments, the system 5 may include a two-way video system that may enable the user 45 such as parents, family members and/or caregivers associated with the baby 15 to have two-way communication with the baby 15. The two-way video system may project a video image of the user 45 on any convenient flat surface in the vicinity of the baby. A video image of the baby may be displayed to the user via any convenient screen such as, for example, a computer display (e.g., laptop, desktop, and/or tablet) or the GUI 55 of the mobile phone 50.

In some embodiments, the system 5 may be configured to provide stimulation and education to the baby. Images may be shown, for example, with a voice telling the baby what the image is via the speaker 16. The monitoring systems (e.g., the BMID 10) may be configured to determine, from the baby's reactions such as, for example, its eye movements, body movements, and/or the baby's voice, whether the baby 15 is paying attention to the displayed images or sounds, and whether the baby 15 is understanding what the baby 15 sees. The system 5 may also be configured to determine, for example, by the baby's eye movements and/or body movements, if the baby is getting bored and the BMID 10 may discontinue the baby-specific educational plan for the baby 15 until the baby 15 shows interest again in the projected image 25. In some embodiments, the user 45 may be alerted via the GUI 55 of the mobile device 50, for example, that the baby has learned a new word or new concept. Therefore, the personalized baby-specific educational plan may be provided for the baby 15, based on AI. In other embodiments, the user 45 via the GUI 55 may be able to the change or tailor the personalized baby-specific educational plan in real time.

In some embodiments, the personalized baby-specific educational plan may be used for many years, for example, with the educational and soothing use cases being altered as the child develops. These stages may be in collaborations with, for example, service providers, subscribers, interactive games, users, or any combination thereof.

In some embodiments, the education, development and entertainment systems based on the personalized baby-specific educational plan may be viewed as a “university” for babies. The use of the personalized baby-specific educational plan for the baby 15 may be free or subscription-based. Subscription-based systems may use business-to-business models or business-to-consumer models for the entertainment and mass media markets.

FIG. 5A is an algorithmic flow diagram 200 of the computer-based system for monitoring and interacting with a baby in accordance with one or more embodiments of the present disclosure. The algorithmic flow diagram may be used to generate training datasets for the machine learning models disclosed herein for each use case. The machine learning models may incorporate the functionality of one or more algorithmic blocks in the algorithmic flow diagram 200 into the machine learning models once trained.

In some embodiments, with regard to a physics algorithm 220 data pipeline, the processor 60 may be configured to process raw sensor data 215 (e.g, video, audio, temperature, light, RF etc) related to either a baby 205 and/or an environment 210 in which the baby 205 is present. Note that the physics algorithm module 66 of FIG. 1 is equivalent to the physics algorithm 220 block of FIG. 5A. The sensor data 215 may be inputted into the physics algorithm 220. The physics algorithm 220 is configured to output baby metadata and environment metadata from which features may be extracted that characterize the baby 205 and the environmental conditions 210. The baby-specific features may include, for example, baby-specific physiological data such as a baby heart rate, a baby heart rate variability, baby temperatures at various locations on the baby's body, baby voice classification data such as the baby's voice rate, voice magnitude and voice pitch, baby motion rate, moving parts, etc. The environmental-specific features may include light intensity, sound, room temperature, etc.

In some embodiments, the physics algorithm 220 may preprocess sensor data by applying filtering, decimation and calibration operations, for example, to the sensor data to generate time waveforms and/or images (videos). The signal to noise ratio of the time waveforms and/or images may be improved by filtering relevant frequency bands of babies for each sensor. Differentiating between environmental data and baby data may be implemented using sensor fusion algorithms, for example, cross correlation of sound transducers oriented at various positions. Then generating signal transformations, for example, by applying using a 1D Fourier transform, 2D Spectrograms, wavelets, 2D/3D fast Fourier Transforms for images and videos, hilbert transform (for envelope signal), cepstrums (e.g., autocorrelated signal balancing), and the like.

In some embodiments, feature extraction algorithms may be applied to the relevant vectors for diagnostics to extract features (e.g., baby-specific features 225 and environment features 230) using basic mathematical operations, such as for example, sound and light mean and root mean squares, probability density function, moments of waveforms, etc. Other baby-specific features may also be extracted using advanced algorithms, such as for example, a baby heart rate may be extracted using Euler magnification of the FFT phase to identify repeated changes and to quantify its heart rate using the (smartbeat) heartbeat detection algorithms as disclosed hereinbelow.

In some embodiments, a baby smile rate may be extracted using a pattern recognition algorithm from the video image data from the imaging camera 81 that identifies smiles segmentation for various face sizes and quantifies its rate. Other features may also be extracted using unsupervised deep learning methods, like convolutional autoencoders, that may extract latent features that describe a baby's state at time of the measurement. These autoencoders may be pre-trained on multi-baby baby dataset queried, for example, from one or more databases 112 stored in the one or more electronic resources 110, data from a plurality of babies with specific meta-features that characterize each baby from the plurality of babies.

In some embodiments with regard to a time driven data pipeline 250, the processor 60 may collect features using the features generated by the physics algorithm pipeline, such as the baby-specific 225 and environmental-specific 230 meta-features, and actions related to the environment (e.g., general environment features 255). The time driven data pipeline 250 may generate a time series X_(i-n),X_(i−n+1), . . . , X(i) for each feature X_(i) where n represent the n^(th) measurement prior to measurement i. (Note that the time driven pipeline module 67 of FIG. 1 is equivalent to the time driven data pipeline 250 block of FIG. 5A.) For the time series for each feature, the time driven pipeline 250 may calculate time dependent (TD) features 270 that characterize feature statistics over time and feature progression. The time-dependent baby-specific features may include the baby-specific features exhibiting a time dependence, such as breathing rate, heart rate, etc. with the exception of the baby static features 245 in FIG. 5A. Similarly, the time-dependent environmental-specific features may include the environmental-specific features exhibiting a time dependence (e.g., time of day, weather, humidity, air pressure, etc). The TD features may be calculated using basic arithmetic operations, like mean, variance, max, min, or percentile(x) of the feature over a window of k recordings. The TD features 270 may be calculated using advanced signal processing functions like calculating probability gradients for n windows in time and taking the maximum (or minimum) gradient. The TD features may also be calculated using sensor fusion algorithms, for example baby motion features relative to environmental-specific features (such as environment sound, light, etc.).

In some embodiments, a baseline 265 may be generated that characterizes a baby state given available information, including actions that were applied to the environment of the baby (e.g., a collection of features 240 and 245, TD features 270, actions 235, and environmental-specific features 255 that reflect a specific window of time). This baseline 265 may be calculated using parametric configuration, such as using k features and TD features 270 for a specific window or the base line 265 be calculated using advanced ML approaches such as deep autoencoder that encode k features and TD features to a specific state for a specific window, or a variational autoencoder that learns the baseline probability density function per specific window. The output of the time driven pipeline 250 may then be relayed to a behavior model pipeline 275 and in addition is being stored in the history bucket (e.g., the feature history 260).

In some embodiments, a behavior model 275 pipeline may collect the output data of the previous data pipelines (features, TD features 270, baseline 265 signature, metadata and actions taken on the environment) to model the behavior of the baby 15. Note that the behavior model 68 module FIG. 1 is equivalent to the Behavior model 275 block of FIG. 5A. The behavior model 275 may generate a model that describes the mental, emotional, and behavioral states of the baby 15 given external conditions (such as environmental states. movie, sound, light, or other external states such as food consumed, time for breastfeeding, etc.).

In some embodiments, the behavioral models may include sub-models such as a stress level model (based on the baby's motion, heart rate (HR), heart rate variability (HRV), cry sound, etc.), a happiness characteristic model (based on smiles patterns, HR, HRV, and sound), sleep characteristic model (total sleep time, time during each sleep mode, number of times of being awakened, etc), and the like. The behavior model 275 may be trained using the input data of the pipeline, and data from a plurality of babies with similar baby-specific characteristics (such as similar age, gender, similar environment characteristics, etc). The behavior model 275 may be built using a supervised approach where the data is trained versus behavior characteristics, or an unsupervised approach where encodes all features to a single state that defines baby behavior.

FIG. 5B illustrates an exemplary wide 340 and deep 330 neural network model 315 to model a smiling rate (node 317) of a baby in accordance with one or more embodiments of the present disclosure. Example of development of such model is taking a wide and deep neural network 315 where the dataset used for training the network is the features, time dependent features, environmental meta features and actions taken, and then training the wide and deep model in a supervised approach against the smiling rate of the baby (with a mean square error (MSE) loss function, for example). In this way, the model may correlate between environmental states (nodes 332, 334, and 336) and happiness characteristics (e.g., the smiling rate of node 317) so later the environmental states may be tuned to improve happiness. Using a wide and deep architecture 315 may capture the importance of environmental parameters on the baby behavioral state. Since the baby 15 is constantly growing and changing, a portion of the training data may include specific baby data and data for similar babies from a plurality of babies which is changing over time to maximize the baby's behavioral and/or emotional state.

In some embodiments with regard to a feedback environment generator 300, the feedback environment generator 300 may compile the user configuration 309 that may be entered via the GUI 55 of the mobile device, for example, by the user 45 (e.g., setting the use case such as soothing, feeding, and/or education) with a digital twin baby 290. The digital twin baby 290 may capture all behavior models 275 and baby-environmental configurations to provide actions based on the baby's environment. The digital twin baby 290 may be a set of parameters representing the baby's different responses to different stimuli when the baby is in different behavioral states taken at different time intervals. The digital twin baby and the user configuration 309 may be inputted to the feedback environment generator 300

In some embodiments, the feedback environment generator 300 may output a notification, an action, a recommendation, or any combination thereof so as to change the behavioral state of the baby over time to a desired behavioral state (predefined behavioral state) based on the use case. The behavioral states may include for example an agitated state, a calm state, a sleep state, a hungry state, a satiated state, a stress state, a playful state, a non-educated state on a particular subject, an educated state on a particular subject etc. For the soothing use case, the baby's behavioral state may be changed from an agitated state to a calm state (the desired behavioral state). For the feeding use case, the baby's behavioral state may be changed from a hungry state to a satiated state (the desired behavioral state) via the user's action in feeding the baby in response to the system automatically preparing the foodstuff (e.g., warming the baby's milk, for example). For the education use case, the baby's behavioral state may be changed from a non-educated state on a particular subject to an educated state on the particular subject (the desired behavioral state).

In some embodiments, examples of actions outputting from the feedback environment generator 300 may be, for example, reducing/increasing the intensity of light, changing light color, playing a sound (like a voice of a mother, a family member, a woman, a man, or a song, or any other source of digital sound), projecting a movie on the ceiling, do nothing, stop the current action, etc. Outputted notifications may include sending a notification such as an alert to the user 45 on GUI 55, for example that the baby is hungry. Outputted recommendations may include to do nothing, stop current action, or change the baby's education curriculum. This may be implemented by using the behavioral model function and optimizing it to a user requested state (e.g., to soothe the baby). The optimization may be done using a minimization of loss function on baby cry features, or baby motion features, or any other behavioral characteristic generated by the behavioral model 275. This process of implementing actions, is repeatedly and iteratively so as to change the state of the baby may be done until the loss function reaches an equilibrium (as defined by the model). The iterative processing may be applied using arithmetic functions, ML model, or reinforcement learning techniques with stochastic parameters added to produce a couple of paths for minimization.

In some embodiments, the algorithmic flow diagram 200 of the computer-based system for monitoring and interacting with a baby may tailored for each of the use cases described herein such as feeding the baby, soothing the baby, or educating the baby based on the training the different models using a training dataset with the input-output data features for each of the use cases as shown, for example, in the exemplary embodiments of FIGS. 4A-4B. The input data features may be the baby-specific features 225 and the environmental-specific features 230 of FIG. 5A that are mapped to the actions 302 and/or IoT Activation 308 based on the output of the feedback environmental generator 302. Examples of the baby-specific features 225 as shown in FIG. 5A may include but are not limited to breathing detection (breathing rate), Heart rate (heartbeat signal data), baby voice (baby voice classification data), baby temperature as shown in inputs 163 and 174 of FIGS. 4A and 4B.

In some embodiments, the baby-specific behavioral state detection machine learning model and/or the baby-specific educational machine learning model may be any suitable machine learning model that may be trained for a specific use case using datasets as shown for example in FIGS. 4A and 4B.

In some embodiments, the baby-specific behavioral state detection machine learning model and/or the baby-specific educational machine learning model may incorporate the functionality of the time driven pipeline 250, the behavioral models 275, and the feedback environment generator 300 such that the baby-specific features 225 and the environmental-specific features 230 are mapped into the actions 302 specific to each use case. Stated differently, for each use case (e.g., soothing, feeding, and education), the blocks shown in the algorithmic flow diagram 200 may be used to generate the use-case specific training datasets for training the baby-specific behavioral state detector machine learning model and/or the baby-specific educational machine learning model.

In some embodiments, the baby-specific behavioral state detector machine learning model and/or the baby-specific educational machine learning model may be implemented using any suitable machine learning model such as a classification neural network model, long-short term memory (LS™) model, convolutional neural network, and/or a multi-class neural network, for example. They may be trained with the training dataset for the particular use case.

In some embodiments, a baby-specific behavioral state detector machine learning model may be used for the soothing and feeding use case. The baby-specific behavioral state detection machine learning model in the soothing use case may map the baby-specific and environmental-specific features into actions such as for example but not limited to generating by the speaker 16, a soothing sound for the baby when the baby is determined to be agitated, to generate by the speaker 16, a sleep-enhancing sound when the system detects that the baby is about to wake-up (so as cause the baby to fall back asleep), and/or to project via a projection device (e.g., the projector 18), a relaxing image to be viewed by the baby. For the feeding use case, the baby-specific behavioral state detection machine learning model in the feeding use case may map the baby-specific and environmental-specific features into actions, such as for example, but not limited to changing the temperature of the foodstuff temperature controller 35 when detecting that the baby 15 is hungry so as to prepare the foodstuff such as the baby's milk in the bottle 32 for feeding the baby.

In some embodiments, a determination that the baby is hungry may include considering time periods in which the baby eats (e.g., every three hours for example), the last time the baby ate and observing that in a time interval before the baby is fed, the baby may exhibit certain movements. This data may be acquired for example over a plurality of babies and for the baby 15 that may be used in training the AI-models such that when the baby 15 exhibits similar movements in a predefined time after the baby last ate, the actions 176 by the AI-model may be to send an alert 140 (user notification) on the GUI 55 on the mobile device 50 of the user 45, for example, that the baby's food is being prepared (FIGS. 2B and 2C), or simply that the baby is hungry. The determination that the baby is hungry may include considering the movement rate, the breathing rate, time of the day, user configuration (user feedback) (such as the user indicating on GUI 55 that the baby was fed 2 hours ago, or that the baby needs to gain weight), baby age, weight, height, for example.

In some embodiments, an identification by the system 5 that the baby is sleeping and/or may be about to wake up and/or has already awakened may include acquiring image and/or audio data for movement and/or skeleton detection, and/or voice classification for the baby 15 and/or for each baby in the plurality of babies. This data may be used in training the AI-models to identify that the baby is agitated and/or about to wake up.

In some embodiments, the feedback environment generator 69 may be trained using data from the plurality of babies as to which audio stream (tune), audio volume, equalizer parameter succeeded in soothing the baby. Soothing the baby as referred to herein may be the iterative process of playing a soothing sound or an audio stream to the baby and/or relaxing images to project to the baby (e.g., the visual image 25 of the rabbit, for example) that causes the baby to calm down and/or fall back asleep. This may be assessed by the AI model from the movement data detected from the image data of the image camera indicating smaller movements and/or the audio data indicating that there is no crying and/or the baby may be determined to have fallen back to sleep, for example. In other embodiments, in the same vein, a sleep-enhancing sound may be any audio stream determined to cause the baby to fall back asleep when the baby is awake or is about to wake up as predicted by any of the AI-models. The AI-model may be trained to output any projection features shown in the output features 165.

In some embodiments, the AI-model may be trained to output a type of vibration (vibration intensity and/or vibration rhythm) for the vibration unit 40 to apply to the baby so as to soothe the baby as described above.

In some embodiments, the baby-specific educational machine learning model for the educational use case when subjecting the baby to a baby-specific educational plan may map the baby-specific and environmental-specific features into actions such as outputting an indication that the baby understood or did not understand a visual image and a sound associated with the visual image based on the baby-specific educational plan as shown for example for the rabbit image shown in FIG. 2D, or may output a baby-specific educational recommendation such as to modify the baby-specific educational plan if it is too hard for the baby or the baby is bored when the baby may be detected to be bored, for example.

In some embodiments, the actions 302, (e.g., environmental changes experienced by the baby 15 shown in the outputs 165 and 176 in FIGS. 4A and 4B, for example) that are predicted by the baby-specific behavioral state detection machine learning model and/or the baby-specific educational machine learning model after training with the training datasets as generated in the algorithmic flow of FIG. 5A as defined above, may be performed iteratively so as to change the baby's behavioral state in accordance with goals of the specific use-case. For example, for the soothing use case, the baby may experience one or more environmental changes by the system 5 performing any of the actions as shown, for example, in list of outputs 165 in FIG. 4A, within a predefined time interval until the baby's behavioral state changes from an agitated state to a calm state (or falls back asleep).

In some embodiments, the machine learning models may dynamically change parameters in the actions until the until the baby's behavioral state changes from an agitated state to a calm state (or falls back asleep). For example, the parameters of the action (e.g., the soothing sound) such as changing an audio file, changing the BPM in the audio, changing the volume, changing the audio stream, and/or changing the equalizer parameters may occur multiple times in the predefined interval based on the changing output of the baby-specific behavioral state detection machine learning model.

In some embodiments, the AI-based system may generate an infant condition description vector (ICDV). The ICDV may include a historic and current representation of the baby's emotional status. The ICDV may include current sensor data and a history of the Infant (IH). Current sensor data may include data from many sensors, may be processed or raw data, may be a continuation of immediate history data, or any combination thereof. Typically, the sensor data may be processed into different signals of interest, such as for example a heartbeat signal. The new data may be concatenated to the previous data, thus forming a continuation of immediate history data.

The infant history (IH) may include 3 parts:

a. Bio history (IBH) data that may include baby-specific personal data such as the baby's age, physical characteristics (such as for example height, weight, head size, etc.) and developmental stage (such as for example movement capability, communication level, sleep ability, melatonin state estimation, etc.) b. Infant personal history data (IPH) may include baby-specific historic responses to the reaction loop, generated from historic data specific to this baby. c. Infant crowdsourcing historic data (ICH) may include a historic weighted average of the responses of other babies (e.g., data from a plurality of babies), taking into consideration the IBH and IPH of the other infants. The infant crowdsourced data can be from other babies using the system, from laboratory experiments, and any combination thereof.

The results from each agent may be relayed to the Response         Recipe Calculator 625 to generate an action list for each         response system and to transmit it through the Response API Pool         626, as well as to update the actions, the IPH and the ICH         through the Prior-Data Gate 620.         II Reaction/Soothing     -   E. Activate at least one of the following functions:         a. Activate a soothing method 614     -   i. Soothing by sound from the speaker such as for example,         music, white/pink noise, a user's voice, or any combination         thereof. The voice may be recorded, live or both although,         typically, a recorded voice message may be used. The volume,         type of sound and length of time the sound is emitted may be         varied, depending on the baby's reaction.     -   ii. Activate the projector and display a soothing video.     -   iii. Activate a vibration unit.         b. Activate a functional IoT device 615     -   i. Activate a foodstuff temperature controller 35 to warm-up,         for example, a foodstuff, typically a bottle of milk.     -   ii. Control an ambient light (e.g., the illumination lamp 27)         such as for example, turning a light on or off, adjusting a         lighting level, and/or change the color of a light.     -   iii. Activate another IoT device.         c. Send a notification to a user 616     -   i. Send the notification via a mobile application (e.g., display         on the GUI 55 of the mobile device 50), for example, an app, a         built-in OS notification, or any combination thereof     -   ii. Send the notification by a phone call (e.g., to the mobile         device 50).     -   iii. Send the notification by sound from the speaker system         (e.g., the speakers 16).     -   F.

Based on the sensor data from step E, using AI, automatically         modify the soothing method 617.     -   H. Based on the modified parameters of step (E) and the results         of step (F), repeat step D.     -   I. Send the modified parameters to the crowdsourcing soothing         method server 611 for modification of the generic soothing         method decision-making component (AI\machine learning).

In some embodiments, the optical subsystem 482 a may include both a visible-spectrum imaging detector (for daytime use) and an infrared imaging detector for night vision. In other embodiments, computer vision motion detection may also be used, either integrally with the optical system, as part of the processing unit, or any combination thereof.

User interfaces may be for example a smartphone app, a telephone messaging system, a computer messaging system, the GUI 55, or any combination thereof. Examples of computer messaging systems may include an email messaging system, audible alerts, visible alerts, and/or a computer-based interface. A Smartphone app and a telephone messaging system may use audible alerts, visible alerts, tactile alerts, or any combination thereof, to inform a user of an incoming message, to provide a message, or any combination thereof.

In some embodiments, the temperature controller 485 (e.g., foodstuff temperature controller 35 from FIG. 1) may be configured to store feeding consumables and to keep the feeding consumables at a predefined temperature. The feeding consumables may be milk, either breast milk or a prepared manufactured infant milk (formula) or milk substitute, water for preparing formula or milk substitute, and/or a foodstuff. The feeding consumable may be kept cold until time of use and may be heated to an appropriate temperature at the time of use.

In some embodiments, either the temperature controller 485 or the processing unit 481 may determine from the behavior of the monitored person (e.g., the baby), that a feeding time is imminent, and may provide a mechanism for warming the milk to an appropriate temperature for use. In other embodiments, the system may include mechanism for alerting the user 45 (e.g, parent or other caregiver) that a feeding time is imminent such as via the GUI 55 on the mobile device 50. In yet other embodiments, the system may include a mechanism for determining that the parent or other caregiver may be approaching the monitored person (e.g., the baby) to feed the monitored person. Stated differently, the system 5 may monitor the distance D as shown in FIG. 1 that the user 45 may be approaching the baby 15.

In some embodiments, the temperature controller 485 may include both a heating and a cooling mechanism, such as for example a Peltier device for both heating and cooling, although separate heating and cooling devices may be used. Heating devices may include for example a Peltier system, an infrared heater, a heating mantle, a heating tape, a microwave, hot air, or any combination thereof. Cooling devices may include for example a Peltier system, a cooling mantle, cold air, a circulating cold liquid, evaporative cooling, or any combination thereof.

In some embodiments, the processing unit 481 may be integral to the monitor, may be a component separate from the unit, may be part of the cloud, or any combination thereof. The processing unit may collect, process data and may provide feedback from the collected data to subsystems, such as the temperature controller (e.g., the IoT activation 308 from FIG. 5A) and to a user (e.g., the user 310 from FIG. 5A).

In some embodiments, by collecting various data from the baby and its environment, the system 480 may provide personalized feedback on the baby to the user. The data collection performed by the monitor 482 and/or by other sources (for example, a speaker 484, a microphone 484 a, a thermometer 482 b and user input) may include, for example, monitoring breathing, acoustic and visual monitoring, heart rate and temperature monitoring, feeding schedule, sleep routine, signals of crying, and more. From these, the processor may determine, for example, breathing patterns and changes in breathing patterns, acoustic patterns and changes in acoustic patterns, movement patterns and patterns and changes in movement patterns, body temperature and changes therein, heart rate and changes therein, or any combination thereof.

In some embodiments, the processing unit 481 may continuously collect and process data for feedback in order to generate an automated personalized solution. Information gathered from the user may be used to activate various system functions to provide a custom-made solution for a variety purposes implementing the feeding, soothing, inducing sleep, and/or education use cases. The system 480 may be connected to a user-friendly user interface 486.

In some embodiments, information gathered from the user via the monitor may processed via the machine learning models/algorithms (e.g., the MLM/Algorithms 65 of FIG. 1). The processed information may be used to activate various system functions that may provide custom-made solutions for the feeding, soothing, encouragement to sleep, and/or education use-cases for example.

FIG. 7E schematically illustrates an embodiment of an audio generator response agent for a reaction soothing loop in accordance with one or more embodiments of the present disclosure.

In some embodiments, the audio generator response agent may generate sounds to be played to the baby. The system may perform the following steps:

The predetermined number may be in a range from 0             to 100, in a range from 5 to 20, or the last 10 soothing             sessions.         -   5. Sensor data over a predetermined time previous to the             current time. The predetermined time may be in a range from             0 to 2 hours, from 1 minute to 20 minutes, or the previous 5             minutes data. Typically, baby-specific parameters derived             from the output sensor data may include any combination of             the following:             -   1. Breathing rate             -   2. Heart rate             -   3. Temperature             -   4. Movement map             -   5. Audio waveform, or             -   6. Crying status     -   C. Generate a sound waveform from the ICDV representation 655 by         steps of:         -   a. Based on the sensor data and the IPH data, select the             base waveform that will have the best soothing effect.         -   b. Compare the base waveform to soothing waveforms from the             ICH data and, if needed, to perform small changes to the             waveform according to waveform history in the ICH.     -   D. Send the waveform generated in Step C to the speaker 656         which may play it to the baby, for example, if the baby has not         fallen asleep after a predetermined time (in which case an alert         may be sent to a user), or if a manual “stop” command is issued.     -   E. Measure the response of the baby (repeat steps A and B).     -   F. If the baby is in a steady sleep state, stop the process.     -   G. If the baby is approaching a steady sleep state but has not         yet reached it, make small changes to the waveform 657 based on         changes in the sensor data and how the changes in the sensor         data have affected this baby (IPH) and other babies (ICH) from         the plurality of babies.     -   H. Iteratively perform steps D-G until the process is stopped.

Note that the process above is exemplary and not by way of limitation such that steps may be carried out in a different order and/or more or fewer steps may be used.

Feeding/Bottle Preparation

In some embodiments, behavioral patterns and parameters of the baby's feeding routine may be determined from the baby's breathing and sleeping pattern, heart rate and other factors. These may be determined from monitor data transferred to the processing unit and from data provided by a user via the user interface 486. In the processing unit, the system (implementing machine learning) may learn how to detect feeding time, detect feeding time and alert the user that it is feeding time, or activate a heating feature of the temperature controller 485 independently to prepare a bottle to feed the baby.

Soothing/Sleep Support

In some embodiments, once the system detects that the baby is about to awaken by detecting increased breathing rate 482 d, changed vital signs 482 b and 482 c, or pre-learned signals, or crying via sound detection analysis, the system may mimic the sounds that the baby heard in the womb to soothe and calm the baby, and/or to return the baby to sleep, reducing the need for parents to wake up during the night. The soothing system may be personalized to increase the effectiveness of the soothing sound for the baby. The soothing sound may include, for example, tones, rhythms, audio effects, and the like. The speaker system may be attached to the monitor or may be a separate personalized soother. The speaker system may be locally in the vicinity to the monitor, or may be remote from the monitor, but close to the baby for daytime use. In addition to the speaker, a projector may add a visual dimension to the soothing system in which the personalized data collected may display the image most soothing to the baby. This may be manually or automatically provided. Both the speaker and projector may be charged when connected to the monitor or separately (e.g., the speaker and/or projector may include a battery).

In some embodiments, the vital signs may include an average heart rate, a maximum heart rate, a minimum heart rate, an inconsistency in the heart rate, an indication that the heart has stopped, an average breathing rate, a maximum breathing rate, a minimum breathing rate, an inconsistency in the breathing rate, an indication that breathing has stopped, a rate of change of the heart rate greater than a predetermined amount, a rate of change of the breathing rate greater than a predetermined amount, or any combination thereof. An inconsistent heart rate may be for example where the heart periodically misses a beat, or the heart beats at one rate for a time, then switches to a second rate. An inconsistent breathing rate may be for example where there are short periods of breathing apnea, or the baby breathes at one rate for a time, then switches to a second breathing rate.

In some embodiments, reaction signs may include data from the vital signs, movement of the eyes, movement of a body part, sounds emitted by the baby, a reaction to a scheduled occurrence, a reaction to a soothing method, a change in behavior over time, or any combination thereof. A sound emitted by the baby may include crying, mumbling, chattering, talking, breathing, screaming, or any combination thereof. A reaction to a soothing method may include lying down, closing eyes, blinking, ceasing to cry, moving into a predetermined sleeping posture, or any combination thereof. The predetermined sleeping posture may be determined from machine learning algorithms trained from previous event data when the baby was asleep.

Education/Communication

In some embodiments, utilizing a projector 483, either 2D or 3D (for example, a hologram) and based on machine learning models trained to assess the baby's attention and interest determined from any of the baby's eye movements, body movements and body positions, the type of eye movement (voluntary or involuntary), vital signs (such as, but not limited to, heart rate, change in heart rate, breathing rate, change in breathing rate, and temperature), reactions (such as, but not limited to, a startle reaction, a reaction to discomfort or pain, looking towards someone or something, looking away from someone or something, a reaction of pleasure and any combination thereof), and developmental stages, the system may allow the baby to communicate with remote family and build educational skills such as for example for understanding shapes, animals, objects, and the like.

In some embodiments, a type of eye movement may be for example, saccades, smooth pursuit movements, vergence movements, and/or vestibulo-ocular movements.

In some embodiments, the projector 483, monitor 482 and speaker (acoustic audio detector/microphone 484 a) may also be configured to function as a proactive training system. Based on vital signs, reactions, video (movement and eye movement detection), and audio information received, data may be collected and analyzed using machine learning models and algorithms to personalize different training programs and to provide feedback to the user (parent or caregiver) on the baby's ongoing development.

Contactless Heart Rate and Blood Oxygen Measurement

In some embodiments, the blood oxygen level and the heart rate may be determined by photoplethysmography (PPG), which uses light and optics to measure properties of the blood. As blood enters and leaves the capillaries of the skin, varying amounts of light may be absorbed by the hemoglobin. The processor may use the amount of change in reflected light from the baby's skin to determine the blood oxygen level, and the period of the change in hemoglobin level to measure the rate at which the heart is pumping. Reflectance-mode PPG may be measured over large distances. The basic optical detection device for this type of measurement may be a simple webcam or an imaging device such as a camera on a mobile device. The light source may be ambient light in a room.

In some embodiments, the heart rate may be determined from skin pixels of image data of the baby's face. In other embodiments, PPG measurements from other parts of the body may used. In yet other embodiments, a gradient-descent algorithm with machine learning may be used to find the heart rate.

In some embodiments, the heart rate determining algorithm may first distinguish the skin pixels from non-skin pixels, which may be for example, hair, eyes, clothing and ornaments, or background objects such as for example, bedding, floors, walls, doors, or furniture. The output from the tracker may be analyzed and a background signal may be estimated.

In some embodiments, in the next stage of processing, the signal may be passed through a zero-phase Butterworth bandpass filter with a pass band of 40 to 180 beats per minute. A Fourier transform may be applied to the filtered signal to determine the heart rate. Typically, this process may be repeated about once a second. The frequency of determination may be in a range of once every 0.1 s to once every 20 s. In other embodiments, a state machine may pause the operation of the algorithm when movement occurs that may not be adequately compensated for by the tracker or by background signal removal, and then the state machine may re-start operation when the undesired movement has ceased.

In some embodiments, when the system 480 may detect dangerous conditions such as a breathing anomaly, for example, the system may determine a severity of the condition and may alert the user 45 accordingly via GUI 55, for example, upon the system assessing to transmit an alert triggered by a severity level decision. Image processing techniques may enable accurate and timely detection of heart rate and breathing from images. These detections may enable powerful monitoring and alerting in the infant sleep context. False negatives may be kept as low as possible, while avoiding false positives (false alarms).

In some embodiments, the system may detect posture of the baby.

In some embodiments, the system may alert a user if breathing or heartbeat rates are outside a predetermined range.

In some embodiments, the camera may include additional features, such as night vision, storage for videos and photos, as well as digital zoom. The night vision feature may allow the user such as a caregiver to obtain a clear view of the baby even in the dark that may be seen in region 57 in the GUI 55 of the mobile device 50. Digital zoom may allow a close-view of the baby and the vicinity of the baby in the region 57 in the GUI 55.

In some embodiments, the system may further include a thermal camera, able to detect if the head of the baby is covered, and to send an alarm to the user's mobile device 50 (e.g., a caregiver mobile device).

In some embodiments, the system may further include sensors, for monitoring the baby and the baby's environment. These sensors may include heat sensors, motion and sound sensors. Data obtained from these sensors may be communicated to the user's mobile device 50 (e.g., a caregiver mobile device).

FIG. 8A illustrates a second embodiment of a baby monitor and interaction (BMID) device 1000 in accordance with one or more embodiments of the present disclosure. The BMID 1000 may include a monitor 1010, smart objects 1020, and a mount 1030 for mounting the device. The monitor may include an optical subsystem, a two-way speaker or a two-way audio system (which may include a microphone and acoustic/audio detector, or any other two-way audio communication system), a projector, a microphone, an acoustic/audio detector, a breathing detector, a temperature detector, a heart rate detector, a user interface, a processing unit, an electromagnetic detector, or any combination thereof.

FIG. 8B illustrates a third embodiment of a baby monitor and interaction device (BMID) 2000 in accordance with one or more embodiments of the present disclosure. The BMID 2000 may include a camera/projector 2020, at least one sensor 2030, and a microphone/loudspeaker 2040. A mount for the device is not shown.

FIG. 9A is a flowchart 2200 of a method for educating a baby in accordance with one or more embodiments of the present disclosure. The user may select a curriculum from suggested curriculums 2201. The curriculum may also be referred to herein as a baby-specific education plan. An appropriate curriculum may be selected from possible curriculums provided by the system via the GUI 55 of the mobile device 50 associated with the user. Choice of curriculum may be based on the age of baby, and cognitive abilities, as estimated by the user (e.g., caregiver). Based on the selected curriculum, the user may attach the related smart objects (e.g., the smart objects 1020) to the arms of the BMID device 2202. The curriculum may be selected based on the age of the baby. Thus, for example, black and white objects may be selected for a newborn, and colored objects may be selected for an older baby.

In some embodiments, an example of a baby-specific education plan or curriculum may include projecting a particular visual image to the baby in different categories such as different animals (dog, cat, the rabbit 25), different people (picture of mother, father, siblings, friends, etc), different objects (car, microwave oven, cake mixer, etc), natural events (wind, water and fire, for example) and to project the visual image with while an playing an sound associated with the projected visual object. The baby may then be subject to looking at two projected visual images, a first visual image and a second visual image while a sound associated with the first image is played from the speaker. The system 5 may assess that the baby understood the correlation between the sound and the first visual image by the image data assessing that the baby made eye movements and/or a head movement toward the first visual image. Similarly, the sound associated with the second image may be played.

In some embodiments, after the baby has been subjected to each visual image and associated sound, the system 5 may project a visual image of the car and determine if the baby made a sound of a car to determine if the baby understood.

In some embodiments, the AI-model (e.g., the baby-specific educational machine learning model) may output an indication or notification on GUI 55 that the baby understood the sound associated with the projected visual image by tracking the eye and/or head movements of the baby. The system 5 may issue a recommendation to the user 45 on the GUI 55 to continue with the current curriculum or modify the curriculum to a more advanced stage. If system assesses that the baby did not understand, the baby-specific educational machine learning model may output a recommendation to the user 45 on the GUI 55 continue with the current curriculum.

In some embodiments, the baby-specific educational machine learning model may automatically modify the baby-specific education plan or curriculum. For example, the modification may include the AI-model (e.g., the baby-specific educational machine learning model) outputting that the baby understood the image-sound pairs presented to the baby and may change the category of images (e.g., animals to household objects), and/or the modification may be inserting a video in place of static visual image, the modification may be saying the word associated with the projected image to see if the baby understand the word “cat” when the system 5 projects an image of a cat and a dog.

In some embodiments, the smart objects 1020 to be attached to the device may include different colored objects, shapes, animals and other suitably shaped objects. In other embodiments, the smart objects 1020 may include a processor used for processing data, storing data and communication. The attached smart objects may then be identified 2203 by the BMID device 1000 or by an application on the mobile device 50 of the user (e.g., a caretaker's mobile device). The user, via an application on a mobile device, may select 2204 one of the attached objects to introduce to the baby. Based on the selection, the device may send 2205 both visual and audible signals, clearly identifying the object to the baby. The visual signals may include movement of the object and/or lighting up the object. The audio signals may include both sounds associated with the object, (e.g. animal sounds for an animal), and voice signals, identifying the object to the baby. The system may repeat 2206 the visual and/or audible signals to the baby at least once. Following the learning session, the baby is tested in order to evaluate baby learning.

FIG. 9B is a flowchart 2300 of a method for testing a baby to evaluate baby learning in accordance with one or more embodiments of the present disclosure. The first step may include activation of the sound signal by the device 2301. No visual signals may be provided. Baby movements in response to the audio signal may be captured by the camera of the device 2302. The data obtained may then be analyzed by video analysis using monitoring software 2303. The monitoring software may use machine learning in order to assess the baby's mental and cognitive development 2304. Comparison data for the analysis may be obtained from a remote platform. Based on the analysis, a customized curriculum 2305 based on the assessment may be tailored to fit the baby's capabilities that may be sent to the user's mobile device 50.

In some embodiments, the system may include a projector, for projecting images onto a surface further away from the baby. The projector may include a 2-way video system with a microphone and a speaker for enabling audio communication with the baby. Utilizing the camera, and video analysis software described hereinabove, the ability of the baby to identify the images may be assessed, in order to provide a curriculum tailored to fit the baby's developmental abilities (e.g., to modify the baby-specific educational plan based on the machine learning assessment of the baby's cognitive development).

In some embodiments, the system may include breathing monitoring functionality. The breathing monitor may include computer vision technology, a motion sensor, a sound sensor, or any combination thereof for detecting movement or sound made by the baby. If no motion by the baby is detected during a predetermined time period, an alert will be sent to a user. The breathing monitor may include a radar or sonar component for detecting movement of the baby. The radar or sonar system may record heart and breathing rates and may send an alert to a user if breathing or heartbeat rates are outside a predetermined range. The radar system may be Continuous Wave (CW) radar, roi radar, Monopulse radar, or passive radar. The radar or sonar detection system may be provided in order to provide a second alarm upon detection of cessation of movement or a reduction in breathing rate. The purpose of the second alarm is to avoid false alarms, since computerized visual systems and baby breathing monitors generally may be prone to false alarms.

Heart Rate

FIG. 10A is a drawing illustrating a heart rate estimation system 3100 in accordance with one or more embodiments of the present disclosure. The heart rate estimation system 3100 shown herein may be used, for example, to determine the heart rate of the baby-specific features 225 as used in algorithmic flow diagram 200 of the computer-based system for monitoring and interacting with a baby or to determine the heart rate needed by any other baby monitoring and interacting processes as disclosed herein. The system 3100 may include one or more electronic devices 3105A,B and one or more subjects 3115. The electronic devices 3105A,B may be a mobile telephone, a tablet computer, a laptop computer, a computer workstation, a video camera, or the like. The electronic devices 3105A,B may capture 3110 a video clip of video data of the subject(s) 3115 using a camera.

In some embodiments, the video data may be captured by one or more of a plurality of cameras, for example, a 3-color channel camera, a multispectral n-channel camera, an infrared camera, a depth camera, a 1-pixel sensor, a servo-controlled camera, or any combination thereof. The 3-color channel camera may be a red/green/blue (RGB) 3-color channel camera. For simplicity, the electronic devices 3105A,B and cameras may be referred to hereinafter in the singular or as an imaging device or imaging camera, although any number of electronic devices 3105 and cameras may be employed.

In the past, it has been impractical to calculate a heart rate from a video data of the subject 3115 because of motion of the electronic device 3105, the motion of the subject 3115, and/or changes in illumination. The embodiments described herein may generate a super pixel model from the video data and may calculate a heartbeat signal and heart characteristics as will be described hereinafter. As a result, the electronic device 3105A,B may accurately estimate the heart rate of the subjects 3115.

In some embodiments, the subjects 3115 may be people or animals. A heart rate may be estimated for the one or more subjects 3115 from the video data. The video data may be captured 3110 from a face or other body part of the subjects 3115. The video data may be captured 3110 from one or more of reflected natural light, reflected electrical lighting in the environment, reflected illumination provided by the system by, for example, lasers or infrared light emitting diodes (LEDs), and/or long-wave thermal infrared emission.

In some embodiments, the video data may be of a motion stabilized region of interest (ROI). The ROI may be any exposed portion of skin, such as for example, at least a portion of the forehead of a subject 3115, at least a portion of a neck of a subject 3115, at least a portion of an arm of a subject 3115, at least a portion of a back of a subject 3115, at least a portion of a chest of a subject 3115, at least a portion of an abdomen of a subject 3115, at least a portion of a posterior of a subject 3115, at least a portion of a leg of a subject 3115, at least a portion of a hand of a subject 3115, at least a portion of a foot of a subject 3115, or any combination thereof. In other embodiments, the pixels may include the ROI to form a continuous portion of the subject 3115.

FIG. 10B is a drawing illustrating an object of interest (OOI) 3285 and a region of interest (ROI) 3250 on a subject 3115 in accordance with one or more embodiments of the present disclosure. In some embodiments, the electronic device 3105 may receive video data and detect the OOI 3285 from the video data. The electronic device 3105 may detect a face, a portion of the face such as a forehead, a neck, an arm, and/or other body part as the OOI 3285.

In some embodiments, the electronic device 3105 may further detect and/or track the OOI 3285. In other embodiments, the OOI 3285 may be detected using cascaded object detection on RGB pixels of the video data. The OOI 3285 may further be tracked with sub-pixel resolution using spatial correlation-based methods. Alternatively, the OOI 3285 may be detected and tracked using infrared band information. For example, a forehead OOI 3285 of the subject 3115 may be identified from an infrared hotspot. The OOI 3285 may also be detected and tracked using multispectral information.

In some embodiments, the OOI 3285 may be tracked from RGB pixels of the video data using facial landmarks. For example, typically via AI, although other optical analysis methods may be used, the electronic device 3105 may identify, typically via AI, the eyes and mouth of a subject 3115 from the RGB pixels and may detect the OOI 3285 relative to the eyes and mouth. Alternatively, the OOI 3285 may be tracked from RGB pixels of the video data using spatial correlation filters.

In some embodiments, the OOI 3285 may be detected and tracked using information from a depth camera. For example, the depth camera electronic device 3105 may identify contours of the subject 3115, and a facial OOI 3285 may be detected from the contours.

In some embodiments, the ROI 3250 may be identified within the OOI 3285. The ROI 3250 may be a specified region within the OOI 3285. For example, the ROI 3250 may be a forehead or cheek of a head OOI 3285. In some embodiments, the OOI 3285 and/or ROI 3250 may be identified from image segmentation. For example, the electronic device 3105 may segment the video data into multiple image segments and may identify the OOI 3285 and/or ROI 3250 from the image segments.

In some embodiments, the OOI 3285 and/or ROI 3250 may be detected using a bounding box. The bounding box may include a luma component, blue-difference chroma, red-difference chroma (YCbCr) color space. For example, the OOI 3285 and/or ROI 3250 may be identified as a region bounded by the YCbCr bounding box. In some embodiments, the electronic device 3115 may detect and track one or more OOI 3285 and may detect and track one or more ROI 3250 within each OOI 3285.

In the depicted embodiment, the super pixel data 3255 may include a super pixel identifier 3215, a time series identifier 3220, measured pixel values 3265, and a plurality of pixel identifiers 3435.

In some embodiments, the super pixel data 3255 may be organized as a data structure in a memory, and may include pixels from any sensor data, as described herein.

In some embodiments, the super pixel identifier 3215 may uniquely identify the super pixel 3240. The time series identifier 3220 may identify a time series 3125 for the super pixel 3240. In some embodiments, the time series identifier 3220 indicates a position in a sequence. Alternatively, the time series identifier 3220 may indicate an absolute and/or relative time.

FIG. 11E is a schematic block diagram illustrating a super-pixel model 3270 in accordance with one or more embodiments of the present disclosure. The super-pixel model 3270 may be organized as a data structure in a memory. In the depicted embodiment, the model 3270 may include a super pixel identifier 3215, a time series identifier 3220, measured pixel values 3265, a background signal 3460, a heartbeat signal 3465, a breathing rate signal 3467, and a sensor noise signal 3470. Sensor signals that may be included are signals that are the result of machine learning such as, but not limited to, a class probability map, a feature map, or any combination thereof. Other sensor signals, as described herein, may also be included in the super-pixel model. The super pixel model may further include signals that are a result of machine learning such as, but not limited to, a class probability map, a feature map, a heat map, or any combination thereof.

In some embodiments, the super pixel identifier 3215 may identify one or more super pixels 3240 that are represented by the model 3270. The time series identifier 3220 may identify one or more time series t 3125 represented by the model 3270. For example, the time series identifier 3220 may identify 48 time series 3125 captured during a two second video clip. The measured pixel values y_(i)(t) 3265 may include pixel values for each pixel 3225 i in each time series t 3125. The background signal u_(i)(t) 3460 may estimate a contribution to the measured pixel values 3265 due to movement and lighting variations captured by the electronic device 3105 for each pixel 3225 i in each time series t 3125.

In some embodiments, the heartbeat signal h_(i)(t) 3465 may estimate a contribution to the measured pixel values 3265 due to a heartbeat for each pixel 3225 i in each time series t 3125. The sensor noise signal n_(i)(t) 3470 may estimate contributions to the measured pixel value 3265 due to sensor noise in the electronic device 3105 for each pixel i 3225 in each time series t 3125. Thus, the super-pixel model 3270 for a time series t 3125 may be modeled using Equation 1. 1. y _(i)(t)=u _(i)(t)+h _(i)(t)+n _(i)(t)  Eq. 1

In some embodiments, the sensor noise signal 3470 may be assumed to be independent, identically distributed Gaussian noise. In addition, the background signal 3460 may be assumed to be smooth. For example, the change in the background signal 3460 between time series 3125 may be assumed to be less than a background threshold. In some embodiments, the background signal 3460 may be modeled as a first-order Markov random process. The background signal 3460 may be modeled using an auto aggressive model of the first order Markov random process. In some embodiments, the heartbeat signal 3465 may be assumed to be the same in each super pixel 3240. For example, h_(i)(t)=h(t) may be assumed to be true for all i.

FIG. 12 is a flow diagram illustrating a heart rate estimation process 3101 in accordance with one or more embodiments of the present disclosure. The process 3101 may be performed by the electronic device 3105. The process 3101 is described in more detail in FIG. 14. In the depicted embodiment, an OOI module 3320, an ROI module 3325, a super pixel calculator 3330, a pre-processor 3335, a modeler 3340, an optimizer 3345, and/or a heart rate detector 3350 may perform the process 3101. The OOI module 3320, ROI module 3325, super pixel calculator 3330, pre-processor 3335, modeler 3340, optimizer 3345, heart rate detector 3350, breathing rate detector 3355 and/or any other detector may be implemented in semiconductor hardware and/or code executed by a processor.

In some embodiments, the OOI module 3320 may receive the video data 3120 from a camera of the electronic device 3105 and detect an OOI 3285. The OOI module 3320 may track the OOI 3285 using the camera and generate OOI data 3440 that describes the OOI 3285. The ROI module 3325 may receive the OOI data 3440 and identify an ROI 3250 within the OOI 3285. The ROI module 3325 may generate ROI data 3425 that describes the ROI 3250.

In some embodiments, the super pixel calculator 3330 may receive the ROI data 3425 and generate super pixels 3240 in a super-pixel time series 3195. The preprocessor 3335 may preprocess the super-pixel time series 3195 to remove interfering signals from the super-pixel time series 3195 and generate a preprocessed super-pixel time series 3290.

The memory 3410 may store code. The processor 3405 may execute the code. The communication hardware 3415 may communicate with other devices.

FIG. 14 is a flowchart of a heart characteristic estimation method 3500 in accordance with one or more embodiments of the present disclosure. The method 3500 may remotely estimate heart characteristics such as, but not limited to, heart rate, heart interbeat interval and heart rate variability. The method 3500 may be performed by the processor 3405 and/or the OOI module 3320, ROI module 3325, super pixel calculator 3330, pre-processor 3335, modeler 3340, optimizer 3345, and heart rate detector 3350 in the electronic device 3105.

In some embodiments, the method 3500 may start, in some embodiments, when the electronic device 3105 receives 3505 the video data 3120 from the camera of the electronic device. In some embodiments, the video data 3120 may be received as one or more time series 3125 of pixels 3225.

In some embodiments, the electronic device 3105 may further detect 3510 the OOI 3285 in each image of the video data 3120. The image may include pixels 3225 for a time series 3125. The OOI 3285 may be a subject and/or a body part of the subject 3115 such as a head, a neck, and arm, leg, and/or the like. In some embodiments, the OOI 3285 may be detected using cascaded object detection on RGB pixels of the video data 3120.

In some embodiments, the electronic device 3105 may further track 3515 the OOI 3285 in each image of the video data 3120. In some embodiments, the OOI 3285 may be tracked using infrared band information from an infrared camera and/or a multi-spectral camera. The electronic device 3105 may generate OOI data 3440 that represents the OOI 3285

In some embodiments, the electronic device 3105 may identify 3520 one or more ROI 3250 within the OOI 3285. The ROI 3250 may be a region of a body part such as a forehead, a wrist, and the like. In some embodiments, the ROI 3250 is identified using image segmentation. The electronic device 3105 may generate ROI data 3425 that represents the ROI 3250.

In some embodiments, the electronic device 3105 may generate 3525 super pixels 3240 in each ROI 3250 from the video data 3120 and the ROI data 3425. In some embodiments, each super pixel 3240 may include a specified number of pixels 3225. Alternatively, each super pixel 3240 may be formed of adjacent pixels 3225 with measured pixel values 3265 within a value range.

In some embodiments, the electronic device 3105 may further generate 3530 a super-pixel time series 3195 for a plurality of super pixels 3240 in each image of the video data 3120. In some embodiments, one or more sequential super pixels 3240 may be concatenated to form the super-pixel time series 3195. Alternatively, one or more non-sequential super pixels 3240 may be selected and concatenated to form the super-pixel time series 3195.

In some embodiments, the electronic device 3105 may remove 3535 interfering signals from the super-pixel time series 3195. The removal of the interfering signals may be preprocessing. In some embodiments, the interfering signals may be removed 3535 using de-trending. The de-trending may be performed by modeling the background signal 3460 as a Gaussian process. Alternatively, the de-trending may be performed by decorrelating the super-pixel time series 3195 with auxiliary signals derived from the position of a facebox that bounds a face of a subject 3115 and from other regions in the video data 3120. In some embodiments, removing 3535 the interfering signals from the super-pixel time series 3195 may include band pass filtering to remove signals outside a frequency band of normal heart rate. For example, signals with a frequency below 40 beats per minute (bpm) and above 170 bpm may be filtered from the super-pixel time series 3195.

In some embodiments, the electronic device 3105 may model 3540 the super-pixel time series 3195 as the super-pixel model 3270. In some embodiments, the super-pixel time series 3195 is modeled in the form of Equation 1.

In some embodiments, the electronic device 3105 may calculate 3545 the heartbeat signal 3465 using the super-pixel model 3270. In some embodiments, the heartbeat signal 3465 and the background signal 3460 may be calculated 3545 by optimizing Equation 2 subject to Equations 3 and 4. In some embodiments, the sum on i may be over the plurality of super pixels 3240, and the sum on t may be over the plurality of super pixels 3240 in the time series 3125, λ₁ and λ₂ may be user parameters, H may be an (M+1)× (2L+1) Toeplitz matrix having (i,j)^(th) element h(2L+i−j) for i=1, 2, . . . , M+1 and j=1, 2, . . . , 2L+1, h is an (M+1)×1 vector having i^(th) element h(L+T+i−1) for i=1, 2, . . . , M+1, and ∥⋅∥⋅ may be a nuclear norm.

$\begin{matrix} {{\underset{{u_{i}(t)},{h(t)}}{\min ❘}{\sum\limits_{i}{\sum\limits_{t}{❘{{y_{i}(t)} - {u_{i}(t)} - {h(t)}}❘}^{2}}}} + {\lambda_{1}{\left\lbrack {H❘h} \right\rbrack }_{*}} + {\lambda_{2}{\sum\limits_{i}{\sum\limits_{t}{❘{{u_{i}\left( {t + 1} \right)} - {u_{i}(t)}}❘}^{2}}}}} & {{Eq}.2} \end{matrix}$ $\begin{matrix} {\lbrack H\rbrack_{({i,j})} = {h\left( {{2L} + i - j} \right)}} & {{Eq}.3} \end{matrix}$ $\begin{matrix} {\lbrack h\rbrack_{i} = {h\left( {L + T + i - 1} \right)}} & {{Eq}.4} \end{matrix}$

In some embodiments, alternatively, the heartbeat signal 3465 and the background signal 3460 may be calculated 3545 by optimizing Equation 5, where D is given by Equation 6 and P is given by Equation 7, and α and β are user selectable constants that may generate the smoothness of the background signal 3460 and/or the predictability of the heartbeat signal 3465. The vector u may include samples of the background signal and the vector h may include samples of the heartbeat signal. The prediction coefficients p_(L), . . . , p_(−L) may be interpolation coefficients derived from a hypothesized period of the heartbeat signal 3465 and the placement of the −1 in the P matrix may also be dependent on the hypothesized period of the heartbeat signal 3465. This optimization may be repeated for a series of different heartbeat periods and a first heartbeat period giving the smallest objective value that may be chosen as the period of the heartbeat signal 3465.

$\begin{matrix} {\min_{u,h}{{\begin{bmatrix} y \\ 0 \\ 0 \end{bmatrix} - {\begin{bmatrix} I & I \\ {\alpha D} & 0 \\ 0 & {\beta P} \end{bmatrix}\begin{bmatrix} u \\ h \end{bmatrix}}}}} & {{Eq}.5} \end{matrix}$ $\begin{matrix} {D = \begin{bmatrix} {- 1} & 1 & & & \\  & {- 1} & 1 & & \\  & \ddots & & \ddots & \\  & & & {- 1} & 1 \end{bmatrix}} & {{Eq}.6} \end{matrix}$ $\begin{matrix} {P = \begin{bmatrix} p_{L} & \ldots & p_{- L} & 0 & 0 & {- 1} & 0 & 0 & 0 \\  & \ddots & & \ddots & & & \ddots & & \\  & & \ddots & & \ddots & & & \ddots & \\ 0 & 0 & 0 & p_{L} & \ldots & p_{- L} & 0 & 0 & {- 1} \end{bmatrix}} & {{Eq}.7} \end{matrix}$

In some embodiments, the electronic device 3105 may calculate 3550 the heartbeat characteristics from the heartbeat signal 3465 and the method 3500 ends. The heartbeat characteristics may include the heart rate 3480, the inter-beat interval 3475, and/or the heart rate variability 3490. The electronic device 3105 may calculate 3550 the heart rate 3480 using one or more of a machine learning analysis of the heartbeat signal 3465, a peak of a Fourier transform of the heartbeat signal 3465, a power spectral density of the heartbeat signal 3465, a zero crossing rate of the heartbeat signal 3465, and/or a sliding correlation analysis of the heartbeat signal 3465.

The embodiments disclosed herein may detect the OOI 3285 from video data, may track the OOI 3285, and may identify the ROI 3250 within the OOI 3285. The embodiments disclosed herein may further generate super pixels 3240 from pixels 3225 within the ROI 3250. In addition, the embodiments herein may be used to generate a super-pixel time series 3195 and to model the super-pixel time series 3195 as a super-pixel model 3270. The super pixel model 3270 may be used to calculate the heartbeat signal 3265 and other heart characteristics. As a result, the embodiments may remotely estimate a heart rate 3480 of one or more subjects 3115. The embodiments may allow, for example, the heart rates 3480 of animals to be remotely estimated, the heart rates 3480 of human subjects 3115 to be estimated in situations where the subjects 3115 may be active, and for the rapid determination of the heart rate 3480. As a result, the embodiments described herein may provide a practical and effective way for remote estimation of heart rates 3480.

Breathing Rate

FIG. 15A is a schematic block diagram of a breathing event identification system 4100 in accordance with one or more embodiments of the present disclosure. The breathing event identification system 3100 shown herein may be used, for example, to determine the breathing detection for the baby-specific features 225 as used in algorithmic flow diagram 200 of the computer-based system for monitoring and interacting with a baby or to detect the baby's breathing rate as needed by any of the other baby monitoring and interaction processes as disclosed herein. The system 4100 may identify a breathing event and/or large-scale motion of a subject 4110 from a video stream of the subject 4110 captured by a camera 4105. In addition, the system 4100 may generate an alert if no breathing event is identified and no large-scale motion is identified. In some embodiments, the system 4100 may also include a monitor device 4123. The monitor device 4123 may include the camera 4105, microphone 4115, hardware modules 4116, and/or a motion detector 4117. In addition, the monitor device 4123 may include a display 4119 and/or a speaker 4121. In some embodiments, the hardware modules 4116 may include dedicated semiconductor circuits. The dedicated semiconductor circuits may include a memory. In addition, the hardware modules 4116 may include a computer.

In some embodiments, the camera 4105 may capture a video stream 4120 of the subject 4110. The camera 4105 may employ a bandpass filter in the range of 0.8-2.5 micrometers. In addition, the camera 4105 may employ a Charge Coupled Device (CCD) that is tuned to 1.5 micrometers. The camera 4105 may capture the video stream as infrared image frames.

In some embodiments, when a subject 4110 may be at risk for ceasing to breathe, the subject 4110 may be monitored to identify the breathing rate and/or detect the cessation of breathing so that timely aid may be given. Furthermore, noninvasive monitoring may be used to identify breathing events so the subject 4110 is not disturbed.

In some embodiments, breathing events may be detected optically and audibly. For example, baby monitors may be used to monitor a baby's breathing through a video (sequence of images) of the baby captured by a camera 4105 and/or a sound of the baby's breathing captured by the microphone 4115. Unfortunately, when identifying breathing events, the consequences of both false positives and false negatives may be high that monitoring may need to detect breathing events with extreme accuracy.

The embodiments described herein identify breathing events and/or large-scale motions based on a video stream as will be described hereinbelow. The embodiments further generate alerts, present displays, and present statistics based on the breathing events.

FIG. 15B is a schematic block diagram of a breathing report 4165 in accordance with one or more embodiments of the present disclosure. The breathing report 4165 may be organized as a data structure in a memory. In the depicted embodiment, the breathing report 4165 may include a breath rate 4231, a maximum inter-breath interval 4233, a minimum inter-breath interval 4235, inter-breath interval statistics 4237, an inter-breath interval histogram 4239, and/or apnea event data 4241.

In some embodiments, the breath rate 4231 may represent a frequency of breathing. The maximum inter-breath interval 4233 may specify a longest interval between breathing events. The minimum inter-breath interval 4235 may specify a shortest interval between breathing events. The inter-breath interval statistics 4237 may specify one or more of a mean, average, and mode of intervals between breathing events. The inter-breath interval histogram 4239 may describe the relative frequencies of breath intervals between breathing events. The breath intervals may be organized into one or more ranges.

In some embodiments, the apnea event data 4241 may be calculated from the breath rate 4231, maximum inter-breath interval 4233, minimum inter-breath interval 4235, inter-breath interval statistics 4237, and inter-breath interval histogram 4239. The apnea event data 4241 may be used to identify sleep apnea events.

FIG. 15C is a schematic block diagram of a motion report 4160 in accordance with one or more embodiments of the present disclosure. The motion report 4160 may be organized as a data structure in a memory. In the depicted embodiment, the motion report 4160 may include a motion frequency 4243, a motion magnitude 4245, a motion duration 4247, a sleep length 4249, a sleep quality 4251, and sleep intervals 4253.

In some embodiments, the motion frequency 4243 may describe the frequency of large-scale motions by the subject 4110. The motion magnitude 4245 may describe a number of pixels affected by each motion. The motion duration 4247 may describe the duration from start to end of each large-scale motion by the subject 4110.

In some embodiments, the sleep length 4249 may describe a length of a time interval during which the subject 4110 is asleep. The sleep quality 4251 may estimate the restfulness of the sleep for the subject 4110. The sleep intervals 4253 may describe each interval during which the subject 4110 is asleep.

FIG. 15D is a schematic block diagram of breathing data in accordance with one or more embodiments of the present disclosure. The breathing data may be organized as a data structure in a memory. In the depicted embodiment, the breathing data may include a field of view policy 4261, an event time interval 4263, a breathing event 4265, and a large-scale motion 4267.

In some embodiments, the field of view policy 4261 may specify when the subject 4110 may be satisfactorily viewed by the camera 4105. The event time interval 4263 may specify a time interval during which a breathing event 4265 and/or a large-scale motion 4267 of the subject 4110 may be identified in order to not generate an alert. The breathing event 4265 may be an identified breath by the subject 4110. The large-scale motion 4267 may indicate motion by the subject 4110. The motion may make determining a breathing event 4265 impossible.

FIG. 16A is a schematic diagram illustrating regions 4003 in an image frame 4005 in accordance with one or more embodiments of the present disclosure. In the depicted embodiment, an image frame 4005 is divided into a rectangular grid of one or more regions 4003. In some embodiments, all regions 4003 may have rectangular shapes and may be equal in size.

FIG. 16B is a schematic diagram illustrating regions 4003 in an image frame 4005 in accordance with one or more embodiments of the present disclosure. In the depicted embodiment, an image frame 4005 may be divided into circular shaped regions 4003. The regions 4003 do not overlap and some pixels of the image frame 4005 are not included in any region 4003.

FIG. 16C is a schematic diagram illustrating regions 4003 in an image frame 4005 in accordance with one or more embodiments of the present disclosure. In the depicted embodiment, the image frame 4005 may be divided into circular shaped regions 4003. The regions 4003 may overlap so that some pixels of the image frame 4005 are included in two or more regions 4003 while other pixels are not included in any region 4003.

FIG. 16D is a schematic diagram illustrating user selected regions 4003 in an image frame 4005 in accordance with one or more embodiments of the present disclosure. Using an interface, a user may identify the pixels in the image frame 4005 that may be occupied by the subject 4110 with user input defining a user selected area 4217. When user input is provided, the regions 4003 may be obtained by dividing the user selected area 4217.

FIG. 16E is a schematic block diagram of breathing event identification states in accordance with one or more embodiments of the present disclosure. The depicted embodiment may include a normal breathing state 4201, an alarm state 4203, and a motion state 4205 of a state machine. When normal breathing is detected by the monitor device 4123 while in the alarm state 4203 or in the motion state 4205, the state machine transitions to the normal breathing state 4201. Normal breathing may be indicated by a breath event 4265 within the event time interval 4263. When large-scale motion 4267 is detected by the monitor device 4123 in either the alarm state 4203 or the normal breathing state 4201, the state machine transitions to the motion state 4205. In some embodiments, the large-scale motion 4267 is detected within the event time interval 4263. If normal breathing and motion are not detected by the monitor device 4123 in either the normal breathing state 4201 or the motion state 4205, the state machine transitions to the alarm state 4203. In some embodiments, the normal breathing and/or large-scale motion 4267 needs to be detected within the event time interval 4263 or the state machine transitions to the alarm state 4203. The use of breathing event identification states is described in more detail in FIG. 17A.

FIG. 17A is a schematic block diagram of a breathing event identification process 4103 in accordance with one or more embodiments of the present disclosure. The video stream 4120 of a subject may include image frames 4005 that may be captured by a camera 4105. The camera 4105 may output image frames 4005. Image frames 4005 may be produced in many different formats including color images with red, green, and blue color channels, grayscale images, infrared images, depth images. Some formats may be derived from others. For example, grayscale image frames 4005 may be computed from red, green, and/or blue images.

In some embodiments, a sequence of operations may be applied to extract a breathing signal 4183. The order in which the operations may be performed may vary. A region sums operation 4170 may compute region sums 4002. The region sums operation 4170 may add together all the pixels intensities lying in a region 4003 of the image frame 4005. The regions 4003 may have different shapes. For example, the image frame 4005 may be divided into a rectangular grid of regions as shown in FIG. 16A. The regions may be circularly shaped as illustrated in FIG. 16B-D. The regions may be vertical or horizontal lines across the image. Other contours besides straight lines may also be used. The regions may be overlapping as illustrated in FIG. 16C or non-overlapping as illustrated in FIG. 16B. Not every pixel in the image frame 4005 may need to be included in a region as illustrated in FIGS. 16B-C.

In some embodiments, the selection of regions 4003 may be guided by an input from a user through a graphical user interface as illustrated in FIG. 16D. Once region selection with the user input is performed, the regions 4003 may be held fixed during the remainder of the processing. In some embodiments, computing the region sums 4002 may not be needed. In some embodiments, subsequent operations may be performed directly on the pixel intensities.

In some embodiments, the output of the region sums operation 4170 may be a vector time series 4006 in which there is one element in the vector for each region. When region sums 4002 are not computed, the vector may include one element for each pixel in the image frame.

In the depicted embodiments, the detrending operation 4175 may be applied after computing the region sums 4002. However, the region sums operation 4170 and the detrending operation 4175 may be performed in the opposite order as shown in FIG. 17B. The detrending operation 4175 may remove a signal mean in a region 4003. The detrending operation 4175 may also normalize an amplitude of the signal for the region 4003. In that the region sums operation 4170 may combine pixels spatially across one image frame 4005, the detrending operation 4175 may operate on a signal in the temporal dimension. The detrending operation 4175 may not be needed. In some embodiments, the detrending operation 4175 may not be performed. The dimension of the vector time series 4006 output by the detrending operation 4175 may be the same as its input to the detrending operation 4175.

In some embodiments, the breathing signal operation 4185 may estimate the breathing signal 4183. In some embodiments, a sparse plus low-rank decomposition may be used as illustrated hereinbelow in FIG. 17C. In some embodiments, the breathing signal operation 4185 may use subspace tracking. Breathing may lead to small variations in pixel intensities that may be concentrated in areas of the image frame 4005 that are unknown a priori. Breathing manifests itself as quasiperiodic variations in certain region sums 4002. Not all region sums 4002 may be affected by breathing. In regions where it is present, the phase of the breathing signal 4183 may be opposite to the phase of the breathing signal 4183 in other regions. The breathing signal operation 4185 may automatically combine the region sums 4002 that exhibit breathing and neglect those regions sums 4002 that do not exhibit breathing. This automatic breathing signal operation 4185 may also account for the phase of the breathing signal 4183 in regions 4003 where breathing is present.

In some embodiments, one process for combining the region sums 4002 may be to use a linear combination. The coefficients in the linear combination may be set to include regions 4003 where breathing is present and exclude regions 4003 where breathing is absent. When a coefficient is set to zero, the corresponding region sum 4002 may not be included in the final estimate of the breathing signal. When a coefficient is nonzero, the corresponding region sum 4002 may be included in the linear combination. The algebraic sign of the coefficient (positive or negative) may be used to coherently combine region sums 4002 and to account for the phase of the breathing signal 4183 in each region sum 4002. The weights and/or coefficients in a linear combination of the region sums 4002 may be automatically selected to include regions 4003 where breathing is present and may exclude regions 4003 where breathing is absent. The resulting linear combination may be a scalar-valued time series which is the final breathing signal 4183. Subspace tracking may be used to automatically adjust the coefficients in the linear combination. In some embodiments, singular value decomposition may be used for the subspace tracking.

In some embodiments, an adaptive subspace algorithm such as a Projection Approximation Subspace Tracking (PAST) that is adapted to image processing may be used. The adaptive subspace algorithm may adaptively update estimates of an orthonormal basis for pixel vector space spanned by the incoming pixel vectors. The dominant basis vector learned by the adaptive subspace algorithm may be used as the coefficients in the linear combination. In addition, one of the steps in the adaptive subspace algorithm may be to compute the linear combination. Thus, the adaptive subspace algorithm may compute an estimate of the breathing signal 4183.

In some embodiments, the adaptive subspace algorithm may be applied to the vector of region sums 4002. It may also be applied to the raw pixels in the original image frame 4005. The adaptive subspace algorithm may also be applied to the video stream of moving objects obtained from a sparse plus low-rank decomposition. Alternative algorithms for subspace tracking and subspace updating may also be used.

In some embodiments, after the breathing signal 4183 is estimated, a breathing analysis operation 4195 may be performed and a breathing report 4165 may be produced. The breathing report 4165 may include a variety of information, including a current breath rate 4231. The breath rate 4231 may be saved over a period of time in the breathing report 4165 so that breathing history may be analyzed and reported. Breathing variability may also be reported. Irregular breathing and breathing anomalies may be of interest. Breathing analysis may include the minimum inter-breath interval 4233, maximum inter-breath interval 4235, and/or the inter-breath interval statistics 4237 such as mean, median, mode, standard deviation, etc. The inter-breath interval histogram 4239 may be computed. Apnea events may be counted and time-stamped as the Apnea event data 4241.

In some embodiments, the motion operation 4190 may generate the motion report 4160. The motion operation 4190 may employ the breathing event identification states of FIG. 16E. Breathing may only be accurately measured when the subject is relatively still. When, for example, a sleeping infant rolls over in the crib, the large-scale motion 4267 causes large intensity changes in image pixels that lead to large region sum values. This masks the breathing signal 4183. Therefore, large-scale motion 4267 may be detected. If the subject's breathing stops, a caregiver would want to be alerted in order to respond and resuscitate the child. Information about motion may be included in the region sums 4002. Motion may be detected using a classic hypothesis test. The null hypothesis is where no motion is present. The alternative is that motion is present. Motion may cause a significant rise in the variance of region sums, detecting the motion. Classic detection methods may be applied. Machine learning techniques may also be applied.

In some embodiments, absence of both large-scale motion 4267 and breathing events 265 may indicate that an alert should be generated. The region sums 4002 may be analyzed to detect when all motion and breathing stop. The estimated breathing signal 4183 may provide additional information. The region sums 4002 and breathing signal 4183 may be fed into a motion operation 4190. The motion operation 4190 may employ the breathing event identification states of FIG. 16E. Transitions between the normal breathing state 4201 and the motion state 4205 may be detected by the hardware modules 4116. The alarm state 4203 may be entered when all large-scale motion 4267 goes to zero and when the breathing signal 4183 drops below a prescribed level and/or no breathing events 4265 are detected.

The method 4500 may generate the breathing report 4165, the motion report 4160, and/or generate an alert. The method 4500 may be performed by the monitor device 4123.

In some embodiments, the method 4500 starts where the camera 4105 may capture 4505 the video stream 4120 of the subject 4110. The video stream 4120 may be captured 4505 without disturbing the subject 4110. In some embodiments, the video stream 4120 may be captured 4505 in an infrared spectrum.

In some embodiments, the hardware modules 4116 may verify 4515 that the field-of-view of the camera 4105 satisfies the field-of-view policy 4261. In some embodiments, the field-of-view policy 4261 may be satisfied if the subject 4110 fills at least 10% of the field of view of the camera 4105. The hardware modules 4515 may adjust the field-of-view of the camera 4105 until the field-of-view policy 4261 may be satisfied.

In some embodiments, the hardware modules 4116 may generate 4525 the vector time series 4006 for the video stream 4120. The time vector series 4006 may include a vector for each image frame 4005 of the video stream 4120. The hardware modules 4116 may divide each image frame 4005 into regions 4003. In addition, the hardware modules 4116 may sum the pixel values in each region 4003 as a pixel sum as described for FIGS. 17A-B.

In some embodiments, the hardware modules 4116 may generate 4525 the vector time series 4006 by dividing each image frame 4005 into regions 4003 and removing a signal mean in each region 4003 as described for FIGS. 17A-B. In some embodiments, the signal mean may be removed from the pixel sums.

In some embodiments, the hardware modules 4116 may estimate 4530 the breathing signal 4183 from the vector time series 4006. The breathing signal 4183 may be estimated 4530 from the reconstructed video stream as described hereinbelow in FIG. 19B. In addition, the breathing signal 4183 may be estimated 4530 by applying the adaptive subspace algorithm to each vector of the vector time series 4006. The hardware modules 4116 may further estimate a breathing event 4265 from the breathing signal 4183.

In some embodiments, the hardware modules 4116 may generate 4535 the breathing report 4165. The breathing report 4165 may be generated 4535 based on the breathing signal 4183 and/or the breathing event 4265.

In some embodiments, the hardware modules 4116 may determine 4540 one of a large-scale motion 4267 and a breathing event 4265 of the subject 4110 based on the vector time series 4006 and/or the breathing signal 4183. The hardware modules 4116 may further generate 4545 the motion report 4160 based on the large-scale motion 4267.

In some embodiments, the hardware modules 4116 may generate 4550 an alert and the method 4500 ends. The alert may be communicated through the speaker 4121. In addition, the alert may be communicated through the display 4119. Alternatively, the alert may be communicated through another device such as a mobile telephone.

In some embodiments, the alert may be generated 4550 if both no breathing event 4265 is identified and no large-scale motion 4267 of the subject 4110 is identified within the event time interval 4263. For example, if no breathing event 4265 is identified from the breathing signal 4183 during the event time interval 4263 and no large-scale motion 4267 of the subject 4110 is identified within the event time interval 4263, the breathing event identification states may transition to the alarm state 4203, generating the alert.

FIG. 19B is a flowchart of a breathing event identification method 4600 in accordance with one or more embodiments of the present disclosure. The method 4600 may identify a breathing event 4265 from the video stream 4120. The method 4600 may be performed by one or more of the camera 4105, the hardware modules 4116, and/or the memory 4420 storing code.

In some embodiments, the method 4600 starts and the hardware modules 4116 may extract 4605 the windowed video subsequence 4145 from the video stream 4120. In addition, the hardware modules 4116 may organize 4610 the windowed video subsequence 4145 into the matrix X 4125 as described in FIG. 16A-C.

In some embodiments, the hardware modules 4116 may decompose 4615 the matrix X 4125 into the sparse matrix S 4130 and the low rank matrix L 4135. In some embodiments, the matrix X 4125 may be decomposed 4615 using Equation 1. X=S+L+N  Eq. 8

In some embodiments, the hardware modules 4116 may further initialize matrix S 4130 to S=0. In addition, the hardware modules 4116 may calculate the low rank matrix L 4135 using Equation 2. L=mean(X−S)  Eq. 9

In some embodiments, the “mean” operator may return a matrix L having the same dimensions as the input X−S in which each element on the i^(th) row of L is the mean value (average value) of the corresponding row of the input X−S.

In some embodiments, the hardware modules 4116 may calculate each pixel of matrix S 4130 using Equation 3, where S_({i,j}) denotes the element on the i^(th) row of the matrix S and the j^(th) column of the matrix S, and T is a sparsity threshold. The sparsity threshold may be set such that a specified percentage of elements in a specified matrix is populated.

$\begin{matrix} {S_{\{{i,j}\}} = \begin{Bmatrix} {{X_{\{{i,j}\}} - L_{\{{i,j}\}}},} & {{{if}{❘{X_{\{{i,j}\}} - L_{\{{i,j}\}}}❘}} < T} \\ {0,} & {otherwise} \end{Bmatrix}} & {{Eq}.10} \end{matrix}$ The hardware modules 4116 may iteratively repeat the calculations of Equation 2 and Equation 3 until a stopping condition is satisfied, yielding the sparse matrix S 4130.

In some embodiments, the hardware modules 4116 may further reconstruct 4620 the video stream of moving objects 4150 from the sparse matrix S 4130. In some embodiments, each column vector of the sparse matrix S 4130 may be reconstructed 4620 as a video frame of the video stream of moving objects 4150.

In some embodiments, the hardware modules 4116 may reconstruct 4620 the video stream of moving objects 4150 from a plurality of sparse matrices S 4130 for a plurality of windowed video sequences 4145 and the method 4600 ends. The hardware modules 4116 may combine corresponding vectors of each sparse matrix S 4130 to reconstruct 4620 the video stream of moving objects 4150.

In some embodiments, the hardware modules 4116 may calculate 625 a normalized auto-correlation for each pixel time series of the reconstructed video stream of moving objects 4150. The hardware modules 4116 may identify 4630 a breathing event 4265 in response to an auto-correlation peak for a given pixel of the reconstructed video stream of moving objects 4150 persisting over a specified number of consecutive time periods, and the method 4600 ends. The time lag of the auto-correlation peak may indicate the period of breathing. The reciprocal of the time lag may indicate the breath rate.

In some embodiments, the use of the reconstructed video stream of moving objects 4150 reduces the computational overhead of calculating the breathing signal 4183. As a result, the breathing signal 4183 may be calculated using limited processing power. As a result, the monitor device 4123 may be fabricated at significantly reduced cost. In addition, the monitor device 4123 may consume much less power, and may be powered by a battery. As a result, the utility of the monitor device 4123 may be significantly increased.

FIG. 19C is a flowchart of a breathing event communication method 4700 in accordance with one or more embodiments of the present disclosure. The method 4700 may encode and communicate information based on the breathing event. The method 4700 may be performed by the monitor device 4123.

In some embodiments, the method 4700 starts, and the hardware modules 4116 may encode 4705 a breath rate 4231 from a plurality of breathing events. In other embodiments, the breath rate 4231 may be calculated as a function of an average time interval between each of the plurality of breathing events 4265. The hardware modules 4116 may further encode 4705 the breath rate 4231 as a heat map 4363. In some embodiments, a breath rate 4231 within a normal range may be assigned a first heat map value and a breath rate outside of the normal range may be assigned a second heat map value. Alternatively, the heat map value may be equal to a function of the breath rate 4231.

In some embodiments, the hardware modules 4116 may further encode 4710 the moving objects of the video stream of moving objects 4150 as a heat map 4363. A moving object value for each pixel may be calculated as a function of a number of corresponding pixels in a sliding sparse subsequence 4155 that include moving objects. The heat map value for each pixel may be the moving object value.

In some embodiments, the hardware modules 4116 may overlay 4715 the heat map 4363 on the video stream 4120 for display to a user. The heat map may be overlaid in a channel of the video stream 4120 such as the alpha channel. For example, the alpha channel of an image frame and/or a pixel may be modified as a function of the heat map value for the image frame and/or for the pixel.

In some embodiments, the hardware modules 4116 may present 4720 statistics to the user using the display 4119 and the method 4700 ends. The statistics may be presented 4620 through the r:4 video stream 4120. The statistics may include the information of the motion report 4160 and/or the breathing report 4165.
